Deep Dive: Types of Sealing Tests You Should Know

Let’s look at some common sealing test methods that Kiyo offers, and what they mean for your product: Vacuum Decay Testing A non-destructive method, ideal for packaging that needs to maintain a controlled atmosphere or barrier. It detects even micro-leaks without damaging the original packaging. Pressure Decay / Burst Testing Applies air pressure or vacuum to the package to check for decay or bursting. Perfect for caps, closures, and pressurized packaging. Tracer Gas Leak Detection Uses inert gases (e.g., helium) to identify leaks under high sensitivity. Common in automotive and electronics where precision is key. Dye Penetration & Water Intrusion Testing Dye or water (sometimes with pressure) is introduced to challenge the seal. Crucial for products like vials, ampoules, and food cans. Bubble Emission Test Slightly older but still effective—immerse your sealed product in water and watch for air bubbles indicating leak paths. A quick visual check. Each method suits certain materials, packaging types, or sensitivity requirements. Kiyo’s strength includes helping you choose the right method—and even combining multiple methods—for robust validation.
